Ammonia leak forces evacuation of UW building
MADISON (AP) — People have been allowed back inside a research building at the University of Wisconsin-Madison after an ammonia leak forced an evacuation.
The leak was reported Tuesday morning, June 5th in a room at the Engineering Research Building.
A Madison Fire Department spokeswoman says firefighters used breathing masks as they checked other rooms in the building.
The leak was reported in a laboratory on the ninth floor.
Firefighters entered the building and shut off a 20-pound ammonia tank that was the source of the leak.
The building was returned to the university around 12:20 p.m. No one was hurt.
